Oct. 20, 1931. L. E. BISSELL LAND PACKER Filed Sepc. 17. 1930 Patented Oct. 20, 1931 UNITED STATES PATENT OFFICE LLOYD EDWARD BISSELL, OF ELORA, ONTARIO, CANADA, ASSIGNOR TO T. E. BISSELL COMPANY LIMITED, OF ELORA, ONTARIO, CANADA, A CORPORATION OF CANADA 1 LAND PACKER Application filed September 17, 1930. Serial No. 482,600.

M invention relates to a land packer comprising two parallel rollers each consisting of an axle and a plurality of packing discs mounted thereon, a frame extending lengthwise of the packer above the rollers having a hanger at the middle and at each end, and a rocker arm fulcrumed to each of the end hangers having bearings in which the two axles are mounted for maintaining their assembly with the frame and providing for the free revolutions of the rollers and their united and individual undulations when following the contour of the land; the object of the invention being to provide these rollers with a center bearing brace which will permit of their free revolution and axial movement, maintain their axial parallelism, prevent the springing of the axle and support the frame.

For an understanding of the invention reference is to be had to the following description and to the accompanying drawings in which Fig. 1 is a plan view of the land packer;

Fig. 2 is an end elevation of the same;

Fig. 3 is a vertical section on the line 33 Fig. 1 showing the center bearing brace;

Fig. 4 is a plan view of the center bearing brace; and

Fig. 5 is a fragmentary view of one of the rocker arms, a bearin and two packing discs.

Like characters 0 reference refer to like parts throughout the specification and drawings.

The land packer consists of two parallel rollers A and B and a frame C extending lengthwise of the rollers. When the land packer is of a relatively considerable width the rollers bend and spring apart and the frame sags, and the purpose of this invention is to overcome this tendency of the rollers and frame. To this end the roller A consists of an axle 1 having a plurality of packing wheels or discs 2 mounted thereon separated at the middle into two groups aa with a separation 9 between the groups. The roller B consists of an axle 3 of corresponding length to the axle 1 havinga plurality of packing wheels or discs 5 mounted thereon separated at the middle into two groups bb' with a 50 separation 10 between the groups. The

frame 6 is located above the rollers and extends lengthwise of the packer and beyond the packing discs. At each end of the frame 6 1s a hanger 7 and at the middle is a hanger 8 in line with the separation 9 between the groups a,a, and the corresponding separation 10 between the groups b-b. A rocker arm 11 is fulcrumed to each of the end hang ers and provided with two bearings 12 and 13 in which are mounted the corresponding ends of the axles 1 and 3 respectively and each rocker arm 11 is provided with two stops 15 and 16 for engaging the adjacent hanger 7 and limiting the upward movements of the axles during the undulations of the rollers. v

A center bearing brace 17 is fulcrumed. to the hanger 8 and provided with two bearings 18 and 19. The axle 1 is mounted in and axially movable through the bearing 18 and the axle 3 is mounted in and axially movable through the bearing 19.

The end hangers 7, rocker arms 11 and bearings 12 and 13 maintain the assembly of the rollers with the frame, support the ends of the frame from the axle and provide for the free revolution of the rollers and their" united and individual undulations when following the contour of the land, and [the hanger 8, center bearing brace 17, and bear ings 18 and 19 support the middle of the frame, prevent its sagging, and permit of the free revolutions and axial movements of the rollers and maintain their axial parallelism.

Having thus fully described my invention what I claim as new and desire to se-' cure by Letters Patent is A land packer comprising two parallel rollers each consisting of an axle and a plurality of packing wheels or discs mounted thereon, a frame extending lengthwise of the packer above the rollers having a hanger at the middle and at each end, a rocker arm fulcrumed to each of the end hangers provided with bearings in which the two axles are mounted for maintaining their assembly with tour of the land, and a center bearing brace fulcrumed to the middle hanger having bearings in which the two axes are mounted permltting of their free revolution and axial movement, maintaining their parallelism, preventing the springing of the axles and supporting the frame.
